Personally, I would not want a Supercycle knowing that there are infinitely better used bikes offered, almost daily, just about anywhere. Believe me when I suggest that Supercycles are not super, at all. That said, I got back into bicycling twenty years ago and the bike I bought was a Supercycle. The bike, which was identical to the one I saw at the dump a week or so ago, started to fail in the second week of use...
Even on Ebay, right now, there are better bikes being offered for the price of a big box of beer. Be a bit patient and check Craigslist or Kijiji daily. Something nice will surface in fairly short order. And, it might be a good idea to know what make a vintage bicycle a quality bike -
Vintage Bicycle Quality. Armed with the information in VBC, you will be better prepared to make a good choice and not pay an arm and a leg doing so.
